I've found a great resource to help you review the most important part of your house - your foundation.

It's not a sexy part of the home renovation process. But it is essential to make sure the structure of your house is in good shape.

This information is from the Canada Mortgage and Housing Corporation and it has a great section to help you do your own evaluation of the foundation. There are sections that help you ask the right questions, gives you options, and lets you know what will happen if you do nothing.

"Renovating a full-height basement can add value and extra living space to your house. Even if you don't have a full basement or aren't planning any basement improvements, the foundation of the house is the most important consideration in any renovation. The foundation supports the structure above it and resists the pressure of the soil around it. Fixing any foundation problems before you renovate is essential to preserve the durability and structure of your home."

The foundation for your house may be a full-height basement, a crawl space, a slab-on-grade foundation or even a combination of two or more types. Foundation materials include poured concrete, unit masonry, stone and preserved wood. Each type of foundation or material has its own associated problems.

The most common problems related to structure or soil conditions are:

• Cracks in slabs, walls or footings;
• Crumbling mortar or concrete;
• Unstable or weak soils;
• Uneven settlement;
• Warped or bowed foundation walls;
• Adfreezing (frozen soil sticking to the foundation and lifting it) or frost heaving;
• Low ceiling height;
• Inadequate support of the main floor system;
• Soil gas or radon infiltration;
• Odors or generally poor indoor air quality (IAQ);
• High humidity;
• Pest infestation"

You can read through the sites questions and suggestions. They also provide a Basement Assessment Worksheet to allow you to check off the problems and locations. It's a great way to let you know it's time to bring in professional help.

Here's a sample of the some of the questions, options, and consequences of ignoring a problem:

"Ask Yourself...

• Is there any porous, powdery or crumbling concrete or mortar?
• Are there honeycombs (voids) in the concrete?
• Is the surface layer of concrete breaking off (spalling)?
  

Consider Your Options:

• Patch small areas of crumbled, honeycombed or broken concrete with a cement-based material. Consult a structural engineer for widespread problems.
  

And If You Don't...

• Small areas of crumbled, honeycombed or broken concrete will allow moisture and soil gas to enter. Deterioration may continue, affecting the structural strength of the foundation.
• Large, damaged areas may be unsafe if they don’t adequately support the existing house or proposed renovations."

Check out the site - even if you're not Canadian. There's some really good, useful information there. If you review your foundation and find some problems, you can always use ConstructionDeal.com to help you find a quality foundation repair company.
